Seafood Processing & Aquaculture
In general, effluents are characterised by:
-
Very high COD concentrations​
-
Large amount of oils and fats
-
High protein concentrations from cooking baths
-
High levels of organic matter (Trimmings, bones and soluble substances from offal)
-
High levels of phosphates, nitrates and detergents
​​
​Treatment processes
​
WATER line: SLUDGE line:
​• Pre-treatment ​• Sludge dewatering treatment
​• Homogenisation
​• Physical-Chemical Treatment with DAF
​• Biological treatment with MBR

Dairy Industry
In general, effluents are characterised by:
-
Very high COD and BOD concentrations
-
High conductivity (due to the sodium chloride from the salting of the cheese)
-
Large amounts of oils and fats
-
Specific values of extreme pH levels
-
High concentrations of PHOSPHORUS AND NITRATES
-
High variability, both in flow and composition
